Although the United States has made major medical advances to curb the AIDS epidemic, Tom Frieden, M.D., director of the Centers for Disease Control and Prevention, writes in the New England Journal of Medicine that hundreds of thousands of people in the country still do not receive necessary care. He called for increased use of testing, including the partners of those infected with HIV, and targeted preexposure phrophlaxis for high-risk groups and treatment. "The combination of patient empowerment, community engagement, clinical excellence, and public health focus on outcomes and impact could make management of HIV infection a model for combating other chronic diseases," Frieden and his coauthors wrote.
